LIBRARY

<menu.h>
int

(MENU

int
unpost_menu
(MENU
*menu);
DESCRIPTION
The
post_menu
()
function causes the menu to be drawn on the screen. Any functions defined by
either
set_menu_init
()
or
set_item_init
()
(see menu_hook(3)) are
called before the menu is placed on the screen. The
unpost_menu
()
does the opposite, it removes a menu from the screen. Any functions defined
by both
set_menu_term
()
and
set_item_term
()
(see menu_hook(3)) are
called prior to the menu's removal.
RETURN VALUES

E_OK
- The function was successful.

E_BAD_STATE
- The function was called from within an initialization or termination routine.
E_NO_ROOM
- The menu does not fit within the subwindow.
